To all whom it may concern Be it known that we, HENDRIK JAN J AKOB J ANSSEN, a subject of the Queen of the Neth erlands, residing at Rotterdam, Netherlands, and HEINRICH Bonsanr, a citizen of the Republic of Switzerland, residing at Zollikon- Zurich, Switzerland, have invented certain new and useful Improvements in Receptacles; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form'a part of this specification.

The hitherto known barrels for storing beer and other liquids have usually been made of wood. It has, however, heretofore been proposed to'make such barrels of metal, for instance, iron, steel, aluminium or the like. But, without counting that the cost of production of such barrels is very high, it has been found that metal barrels, and particularly when they are of a large size,.cannot be manufactured in an advantageous manner, it being very difficult to join together the different parts of the barrel in a tight manner. Further, there have to be met considerable difficulties when the barrel has to be fitted up at the place of erection, for instance, in a cellar. The connection of the different parts of the barrel by means of screws or the like has also the drawback, that the cleaning of the inner parts is rendered more difiicult, and that these connection members may cause infection. Also the manufacture of steel-barrels built up ofsingle iron-plates welded together in an autogeneous manner and lined on the inside with a layer of pitch is not advantageous, since too much time and room have to be wasted. Owing to these drawbacks of metal-barrels more atten'tion'has again been paid in recent years to the concrete and in particular to the ferro-concrete. Barrelsmade of ferro-concrete can be manufactured in any size even in cellars; such barrels moreover do not, rust and they involve only small expense. Ilhe construction of reservoirs for fluids to be made of ferro-concrete and provided onthe inside with a lining of pitch or thin. metal walls renders it necessary to use a great-number of wood laggings and scaffolds and the walls of such reservoirs have to be made very thick partly in consideration of the process of manufacturing and partly to provide sufficient room for placing the iron armoring. Further, the manufacturing of the barrel and the hardening and drying of the mate rial used, involve a great waste of time and if the barrel is subjected to an internal pressure, as it is usually the case, there has to be used for the armoring of such barrels of concrete a large quantity of iron. Finally, the inner pressure causes a slight outward deflection of the walls, which can hardly be prevented, so that cracks and leaksare produced. If, for the purpose of eliminating these disadvantages, there would be chosen a round cross-section for the reservoir in which the liquid has to be stored, difficulties in' the manufacturing of such a reservoir would arise, the stamping being rendered more difiicult and expensive laggings and scaffolds having to be provided for.v More over such a construction has the drawback that any pressure arising inside the reservoir sets off tensile stresses favoring the formation of cracks and producing leaks in the interior layers of the reservoir made of concrete.

Theobject of this invention is to eliminate the drawbacks to be found in connection with reservoirs made of ferro-concrete.

The main feature of the invention consists in the use of molding pieces having a shape corresponding to that of the walls and bottoms of the reservoir, said pieces form ing the reservoir when they are joined together. Around the so formed reservoir there is put an armoring, holding together the single pieces of the reservoir while it is- .bullt up. The armormg may also act as a tensioning device, so that it presses together said molding pieces. There might, however, also bG'llSGd. tensioning devices arranged independently from the armoring.

Several barrels made according to the process forming the subject matter of this inventionare shown by way of example in the accompanying drawings, in which:

Figure 1 shows a front elevation: of a first form of a barrel, the round irons embedded in the molding pieces being not shown for thesake of clearness. Fig. 2 shows a plan view of Fig. 1, the tensioning meansbeing shown in dotted lines to simplify the drawing. Fig. 3 shows a crosssection of one end of this barrel. Figs. l, 5, 6 and 7 show details of the barrehFig. 6 beinga -section on the line 66 of Fig. .5. Fig. 8 shows a detail of a second form of a barrel made according to this invention and Fig. 9 shows a section through a third form of such a barrel.

The walls of the reservoir shown in Figs. 17 consist of molding pieces a," as such molding pieces there can be used, for instance, concrete plates provided with an inner lining. The armoring surrounding the barrel consists of a netting made of single wires 1 having a round cross section and embedded in the longitudinal and transverse directions of the concrete plates 6. These plates 6 pressed closely to the plates a are smaller than the latter, in order to provide grooves R in which the wires 9" may be hooked together to form the continuous netting surrounding the whole reservoir. Into the grooves B there are further put additional tensioning straining members arranged independently from said netting. These tensioning members put. around the outer surface of the reservoir or barrel consist preferably of flat-irons f, while the tensioning members put around the bottoms of the reservoir or barrel consist of chains it. The tensioning members have tensioning screws s'provided with a right hand side and left hand side thread, said screws permitting adjustment of the tension. After the erection of the barrel the grooves R are filled out with cement and the surface of the barrel is then polished, so that all ironparts are prevented from rusting and a smooth outer barrel surface is obtained. The insulating substance on the inside of the barrels is flushed at the joints of the molding pieces a and polished, so that also the inside of the barrel forms an entirely smoothosurface. If the molding pieces are 7 made of another material, for instance glass,

the joints are jointed with a suitable cement.

Fig. 7 shows on an enlarged scale a flatiron f provided with a tensioning screw 8 having a left hand side and ari ht hand side thread and further provide with a chain connected near said screw 8 to the flat-iron f.

Fig. 8 shows a single ring of a barrel surrounded by a strongly strained wire winding 1, acting as a straining armoring. This wire winding of iron connects the single elements of the ring ina sure manner and makes the provision of a netting unnecessary. The wire wound around the ring having been elongated to a certain extent,,owing to the strain to which it has been. subjected during the winding operation exerts upon the segments and their joints a great resilient pressure; If the Wire has been wound an equal nian-ner around said ring no varying pressures will be found in said ring. Such a wire armoring makes the provision of any connections between the different segments of the ring entirely unnecessary. In this instance, however, the material of which the segments of the ring are made, must be practically non compressible.

Fig. 9 shows a barrel having'approximately a cylindrical shape, the lower molding pieces of this barrel serving as a support. This shape of the cross-section permits a greater saving of room.

The device according to this invention results in the following advantages: First, no expensive wood laggings and scafi'olds of any sort have to be provided, only a few centers being necessary; second, the time necessary for the erection of the barrel in the cellar is reduced to a minimum; third,

the thickness of the wall may be reduced to. a minimum and still obtain stability; fourth,- the molding. pieces may be provided with the necessary insulating mass while they are manufactured and they may also be made of other materials than concrete, for instance, clay, glass and the like may be used, and fifth, the formation of cracks and leaks is prevented, the inner walls being subjected by the straining deviceto a pressure.
